Structural Engineering

The project comprised the rehabilitation of the existing Route 76 Bridge over Table Rock Lake, with traffic maintained during construction. EDSI, as a subconsultant, was responsible for the structural design of full-depth precast bridge deck panels and cast-in-place deck closure pours, as well as approach roadway design and maintenance of traffic.

EDSI, as the prime consultant, completed the design for the replacement of the Route N Bridge over Contrary Creek. The project included bridge structural design; hydrologic and hydraulic analysis; preliminary and final roadway design; and survey. The bridge is a single-span NU girder bridge on integral end bents supported by H-piles.

EDSI, as the prime and sole consultant, completed the design of two MoDOT replacement bridges in rural Stoddard County. Route T over Turkey Creek is a single-span prestressed concrete spread box beam bridge with integral end bents supported on CIP concrete piles. Route DD over Drainage Ditch No. 1 is a three-span prestressed concrete spread box beam bridge with integral end bents and intermediate bents supported on CIP concrete piles.  Hydrologic and hydraulic analysis was completed for both bridges.  The designs were completed on an accelerated schedule with Signed and Sealed Plans, Cost Estimate, and Special Provisions submitted in less than 5 months after Notice to Proceed.

EDSI, as an On-Call Consultant, completed the design of a replacement retaining wall along Route N and adjacent to a creek. The new wall is soldier pile and lagging wall.  Additional project components consisted of drainage and safety improvements, including riprap, a drainage flume, and pavement grade adjustments, and new sidewalk, barrier, and fencing.
